APPARATUS FOR TRANSFERRING COAL OR OTHER MATERIAL.

SPECIFICATION forming part of Letters Patent No. 773,194, dated October25, 1904.

Application filed March 4:, 1903.

To (LZZ w/mm it may concern:

Be it known that I, JEREMIAH OAurBELL, of Newton, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in Apparatus for Transferring Coal or other Material, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming a part of thisspecification, in explaining its nature.

This invention relates to an apparatus for transferring coal and othermaterial to or from vessels or docks, and it is especially applicable tocases where the coal or other material is to be taken from barges anddelivered through ships side ports or to other comparatively low points.In the drawings it is illustrated as applied to barges employed intransporting coal and as used in transferring coal from said barges inthe operation of bunkering.

It is desirable to effect the coaling of a vessel while it is at itsdock and from either side of the vessel and without requiring a radicalchange in the position of the vessel with respect to the dock. It isalso desirable that the coal should be transferred to the vessel inbarges and that a means for handling the coal in transferring it fromthe barges to the vessel shall be employed which shall be made common toa number of barges. To accomplish this result I employ a barge which mayor may not be used for transporting coal and which for the purposes ofconvenience I have termed the power-barge, which is adapted to carry atransferable tower and grab or other means mounted upon a truck forhandling the coal, an elevator for varying the elevation of said tower,a truck having means for permitting the horizontal movement of the truckand tower, and the engine or motors for actuating the elevator, movinghorizontally the truck, tower, and grab, and for lifting, lowering,opening, and closing the grab. There are used in connection with thispower-barge coal-transporting barges, which are adapted to transfer coaland which are also adapted to be brought into operative relation to thepower-barge and to then receive therefrom the truck, tower, and grab andto to the transporting-barge.

Serial No. 146,186- (No model.)

support the same in any desired position in its length and to permit ofthe operation of the grab in such position in the discharge of coaltherefrom, the elevator of the powerbarge being equipped with a bridgeextending from it beyond one end of the barge to a position over the endof a transporting-barge and carrying rails, and the transportingbargebearing upon its deck rails in continuation of the rails of the bridgeand whereby means are provided for movement of the truck, tower, andgrab from the power-barge This transfer of the truck, tower, and grabfrom the powerbarge to the transporting-barge and its return are made atdifferent levels, for the transporting-barge rises with respect to thepowerbarge as it is unladen, and the truckand tower can only be movedupon a substantially hori- Zontal plane. For this reason the powerbargeis provided with the elevator, which acts to adjust its tower-supportand the bridge to the level of the tracks of the transportingbarge,whatever that may be, so that whatever the difference in level betweenthe two barges may be the tracks whereby the truck and tower are movedfrom one barge to the other may also be adjusted to and held in the samehorizontal plane. The transporting barge is also combined with thepower-barge by means of the truck-hauling chain or rope, and the tower,truck, and grab are always combined with the engine or motor upon thepower-barge, whether they are upon the powerbarge or whether they areupon the transporting-barge. The power-barge also carries the levers orother means for actuating the engines or motors, which are located inthe engineers observation-house elevated at any de sired distance abovethe deck, so that the position of the truck and tower may be changedupon the transporting-barge and the grab then operated all from thepower-barge.

I do not confine myself to the form or kind of coal-handling mechanismand may use any power-actuated mechanism which is adapted to be mountedupon a truck and transferred from the power-holding barge to operativeposition upon a transporting-barge.

In the drawings Ihave representeda tower and grab which is adapted to beused in a narrow space where there is little or no opportunity for theuse of a lateral boom upon which the grab may move transversely thetower and as employed in conjunction with a stationary hopper having anoutlet at one side of the tower vertically adjustable upon it andprovided with an opening and closing bottom or side which opens topermit of the movement of the grab through the hopper and which closesto form a bottom or wall of the hopper during thedischarge of the grab.

Throughout this application I use the term tower in a broad sense andmay embrace thereby, as well as the tower proper, such other features ascrane, endless conveyor, or

other means for hoisting the coal.

I will now describe the invention in detail in conjunction with thedrawings, forming a part of the specification, wherein- Figure 1 is aview, principally in side elevation, of a power-barge andtransportingbarge arranged in operative relation thereto, the truck,tower, and grab of the coal-handling device being represented upon theelevator of the power-barge. Fig. 2 is a view of the power-barge, partlyin cross vertical section and partly in end elevation. Fig. 3 is a viewin horizontal section upon the dotted line 3 of Fig. 1 and in plan ofparts below said line. Fig. at is an enlarged detail view in plan,representing the connection between the bridge and thetransporting-barge. Fig. 5 is a view in cross vertical section upon thedotted line 5 of Fig. a.

Referring to the drawings, A is the powerbarge, and B thetransporting-barge.

U is the elevator of the power-barge. It is arranged at or near one end,preferably the stern of the barge, and is mounted in the l barge to belifted and lowered at will and to be held in any desired position. ithas rails (r running lengthwise the barge and the bridge l), which ishinged at (Z to its rear end to be lifted to a vertical position, andwhichbridge has rails 1/ in continuation of the rails c of the elevator.position rests upon supports 7/ on the deck of the transporting-barge,which are near the end of the barge. The barge has such supports at eachend in order that it may make no difference which end of thetransporting barge is presented to the power-barge for the reception. ofthe truck and tower. The bridge is centered upon the transporting bargeto bring its rails in line with the rails 1/ of the transporting-l argeand also held in such position by means of the conical registering studsZ), fastened to the transporting-barge to point upward and to receivethe conical l sockets (Z carried by the bridge and having their mouthsopening downward. (See Fig.

The elevator has suitable vertical guides c at each corner, which aremounted in vertical The bridge when in operative guideways c in thepower-barge; and 1 have represented as a means for lifting, lowering,and holding the elevator the rods c' one near each corner, each of whichhas an exteriorand driven by the engine E, whereby the nuts are causedto be simultaneously turned in one direction or the other and wherebyalso they are held from turning. Any other construction of elevator and.means for operating it may be used.

F is the tower-truck. It is represented in Figs. .1 and 2 as upon therails of the elevator. It supports the tower G, which consists of twoframes 7 7, connected at their lower ends by the truck and at theirupper ends by the cross connection The frames are separated suf-[iciently to provide a hopper and grab-operating space g", extendingfrom the top of the tower to the truck and open upon both sides. Thetower supports the grab g and the hop per The grab is lowered and liftedand closed and opened by'the usual ropes which extend over sheaves and gto the grab operating engine g". The hopper is suspended in thetower-space by the chains which extend over sheaves g at the top of thetower and sheaves g at the base of the tower to the engine g. By thesemeans the hopper g can be lowered to a point below the lower end. of theframes between which it is held and can then be turned while out of theframes and raised again in a position one hundred and eighty degreesfrom that in which it was hung originally, so that its openingor chutewill point in the opposite direction from that shown in the drawings.Thus the tower may be used to unload on either side of the barge. Thegrab-ropes and hopper-chains are so rove with respect to the engine 7"and are of such length that the grab may be operated upon thetransporting-barge as well as upon the power-barge, and the hopper adjust ed upon the transporting-barge as. well as upon the power-barge. Thetruck, tower, and grab are moved from the elevator over the bridge andupon the tracks of the transporting-barge by means of the rope or chainwhich passes from the engine E in one direction forward over suitablesheaves to the block at the forward end of the transportingbarge, andthence backward to the truck, and it also extends from the engine over asuitable sheave 5 upon the power-barge to the rear of the truck.

H is the engineers or operators post and house, which is mounted at anydesired elevation on the power-barge and from which the engines areactuated which operate to move the truck and tower to operate the graband to adjust the hopper. The powerbarge may also be provided with thetowerbraces I, which are fastened to the barge adjacent to each side ofthe elevator and which by their inner surfaces bear against or come intocontact with the sides of the truck or base of the tower and upon whichthe truck or base of the tower slides and which act as a stay orreinforce for the tower and to prevent it from canting and also as arelief for the elevator in that it assists in an even distribution ofthe truck, tower, and grab upon the elevator and prevents it from beingbrought too much upon any one portion of it.

The rails b of the transporting-barge extend lengthwise the barge eachside of its continuous hatch B, (see Fig. 3,) the hatch running verynearly the full length of the barge and affording means for theoperation of the grab at any point in its length, so that the entirecargo of the transporting-barge is thus made immediately accessible tothe grab. The rails are supported in any desired way and at their endsare suitable guard-rails to cooperate with the ends of the rails of thebridge, which lap the joint and prevent derailment while the truck andtower are being moved over it.

As I have intimated the transporting-barge is preferably of the typeknown as a doubleender that is, the endsare alike and are so constructedthat each. end is adapted to receive and hold the bridge connecting itwith the power-barge and to receive the truck, tower, and grab from suchend.

The operation of the apparatus is as follows: The power-barge is laidalongside the vessel to be loaded, either upon its outside or upon thedock side and generally at the bow end or the end of the vessel that isfarthest within the dock and with its elevator end farthest removed fromthe bow or end of the vessel. The power-barge will then carry upon theelevator the truck, tower, and grab and the bridge D will beheld in anelevated position. The transporting-barge is then moved end on to thestern end of the powerbarge and in such relation thereto that the bridgeD, when brought to the level of its rails, may be lowered thereto andupon the registering stud b to connect the two barges and the rails ofthe elevator with the rails of the transporting-barge. It will beunderstood that if the bridge is not in a position to make a horizontalengagement with the transporting-barge the elevator, with the bridge,truck, tower, and grab, is lifted or depressed as may be required tobring the tracks of the elevator substantially upon the level of thetracks of the transporting-barge. This movement of the elevator iscaused by operating the engine E, and the elevator at the end of saidmovement is held stationary. The draft-rope Q15 is then led from theengine over the block at the farther end of the transporting-barge andback to the truck upon the power-barge and the said engine operated tocause the truck, tower, and grab to be drawn from the'tracks of theelevator over the tracks of the bridge to the tracks upon thetransporting-barge. Of course it will be understood that the rope g isthen used to draw the truck, while the rope making connection betweenthe engine and the rear end of the truck pays out slowly, the truckbeing steadied by the joint action of both ropes and being heldstationary in operative position by them and suitable rail-grips. Theropes and chains connecting the engine g with the grab and with thehopper are also paid out at will, while the truck, tower, and grab arebeing moved from the powerbarge to the transporting-barge, always,however, maintaining an operative relation thereto and so that thehopper and grab, as well as the truck and tower, may be moved oroperated from the power barge, although the apparatus is then beingborne by the transportingbarge. The bridge D may remain in place or maybe turned back upon the elevator as the transporting barge B isdischarged. The level between its rails and those of the elevator willgradually change, so that when the barge is entirely unladen its railswill then be considerably above the level of the rails of the elevatorwhen the truck and tower were moved upon the transportingbarge. As it isthen necessary to move back the truck, tower, and grab to thepower-barge in order that another transporting-barge may take the placeof the unladen one, it is necessary to then move the elevator upward tobring its tracks in level with the new level of the tracks of thetransporting-barge. This is done by the engine E, and the bridge D ismoved to again make connection between the elevator and thetransporting-barge, and the truck, tower, and grab are then movedbackward by the engine E from the rails of the transporting-barge overthe bridge and upon the elevator, the bridge lifted, and the bargedisengaged. The truck, tower, and grab are then held by the power-bargeuntil another transporting-barge is brought in operative connection withthe power-barge, when the method of operation above described isrepeated.

By constructing the tower, locating and constructing the hopper, andoperating the grab as specified it becomes possible to interpose betweenthe vessel and the dock means for discharging barges which may be movedlengthwise the vessel by the means specified between it and the dock andalso to bunker that side of the vessel without moving it away from thedock or interfering with its gang-planks or other connections and theloading or unloading of its cargo, and the same apparatus is asefficient for use upon the outside of the vessel where the conditionsare often such as to call for the advantages obtained by this narrowconstruction.

\Vhile I have described the invention as embodied in a power-barge andtransportingbarge for transferring coal to a vessel and loading itthereon, I would say that I do not confine myself to such use, but mayemploy it for lJIHDSPOltfLbiOD of any material and for loading it uponor unloading it from the transporting-barge in any position where theapparatus may be vertically employed and whether in conjunction with avessel, other barge, or dock. It will be observed that the powerbarge isused in conjunction with a fleet of transporting-barges, all of whichare con structed to have the relation to the powerbarge above indicated.

The position of the hopper in the tower is adapted to be reversed, sothat its outlet shall be from the side of the tower opposite thatrepresented in the drawings. This is for the purpose of permitting theapparatus to be used at will upon either side of a vessel, and the toweris provided with means whereby this reversal of the hopper and itssuspending and adjusting chains may be accomplished, additional pulleysbeing provided for the sus' pending and adjusting chains in the otherposition rendered necessary by the reversal of the hopper. The manner ofmaking this reversal has not been shown in detail in the drawings, as itis believed from what has been said in the specification that it will bereadily understood. This reversal of the hopper does not change theoperating relation between its gates and the grab, the hopper being soconstrueted and hung as to permit of this reversal without, however,varying its operative relation with the grab.

I have shown the hopper-chains brought together and connected with atackle interposed between the end of the chain and the winding-winch ofthe engine, whereby the hopper may be actuated by hand and may besecured in position to the tower or truck by making the hoisting-ropefast to any part thereof and without disconnecting it from thewinding-winch of the engine, if desired.

Nhen the elevator and tower are at one end of the power-barge, it willbe desirable to provide the power-barge with means whereby its end maybe adjusted down or up to preserve the horizontal level of the elevatorand to compensate for the removal therefrom of the weight of the truck,tower, and their appurtenances. This may be done by changing theposition of the ballast carried by the power-barge toward and from thepart of the barge upon which the elevator is mounted or by means ofwater-ballast, and the latter is the means I prefer to use, and I haveshown in Fig. l the power-barge as having at the end carrying theelevator a tank M, which is adapted to be filled with and emptied ofwater in any desired way. The tank is gradually filled as the truck andtower are moved from the power-barge and gradually emptied as the truckand tower are moved upon it.

The means for gradually filling the tank and gradually emptying it, asreferred to, are not shown, because it would be apparent to any oneskilled in the art how this could be done. For example, by attaching ahose to a suitable water-supply controlled by a suitable faucet andallowing the water to run to the extent necessary to maintain the bargeat the proper level and to empty the tank a suitable faucet leadingoverboard therefrom and opened to a suflicient extent will in due timeempty the tank. These means are so well known that drawings of themwould seem to be unnecessary.

Having thus fully described my invention, I claim and desire to securebyLetters Patent of the United States- 1.
